Rather than storing current state, Event Sourcing stores all domain events that affect an entity and replays them to reconstruct state. The author shares experience from building two event sourced systems and demonstrates how to implement event sourced aggregates using PHP. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is event sourcing and how does it differ from traditional state storage? Event sourcing stores all the domain events that affect an entity rather than just its current state, then replays those events to reconstruct the object's state. This contrasts with traditional approaches that store structural, denormalized state directly in relational databases. Though it seems counterintuitive given years of relational schema design habits, the approach is simple, elegant, and powerful in practice. _daily.dev surfaces practical explainers like this for developers weighing event sourcing against traditional persistence._ ## Similar posts on daily.dev - [Event Sourcing: Simple is often enough](https://daily.dev/posts/event-sourcing-simple-is-often-enough-ijvzsfk43) · We Are .NET · 0 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#php](https://daily.dev/tags/php), [#domain-driven-design](https://daily.dev/tags/domain-driven-design) [View this post on daily.dev](https://daily.dev/posts/practical-event-sourcing-4pzatjm1s) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Practical Event Sourcing","url":"https://daily.dev/posts/practical-event-sourcing-4pzatjm1s","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/practical-event-sourcing-4pzatjm1s"},"datePublished":"2026-06-17T11:25:40.168Z","dateModified":"2026-09-13T20:49:56.871Z","description":"An introduction to Event Sourcing as a practical alternative to traditional state-based persistence.
